4 Claims. (Cl. 126340) This invention relates to the general art ofcooking stoves and ranges, having reference more particularly toimprovements in the broiler ovens which usually form a part of suchstoves and ranges.

More specifically, the present invention relates to broiler ovens of abroadly known type wherein a drawer, rack or the like that supports thebroiler grid or other cooking utensil is slidably mounted in the ovenand is operatively connected to the oven door, so that, when the door isopened the drawer or rack is drawn partly out of the oven where thecooking utensil is more accessible, and, when the door is closed, ismoved to normal position in the oven.

Door-actuated devices of this type for withdrawing and returning thedrawer or rack heretofore employed are more or less complicated andcumbersome; and the object of this invention is to provide a verysimple, inexpensive and efiicient broiler oven accessory that willoccupy only otherwise unused space in the oven, will present nointerference with the opening and closing movements of the door, willpresent a desirable combination of strength, rigidity and light weight,and can be easily detached from the door to permit full removal of thebroiler drawer or rack, when necessary for cleaning the same and/or theoven.

A practical and preferred embodiment of the invention is illustrated inthe accompanying drawings, in which- Fig. 1 is a perspective view of agas range embodying my improvement, showing the oven door fully opened,and the broiler drawer and parts carried. thereby partly withdrawn fromthe oven Fig. 2 is a vertical front to rear section, showing in fulllines the door closed, and in dot and dash lines a partly open positionof the door which takes up the lost motion in the drawer withdrawingmeans.

Fig. 3 is a view similar to Fig. 2, but showing the positions of theparts when the door has been fully opened.

Fig. 4 is a fragmentary side elevation of the broiler drawer anddrawer-actuating link, showing the position of the latter when it beginsto Fig. 7 is a perspective detail of a stationary cam that lifts andlowers the inner end of the link during the final part of the doorclosing movement and the first part of the door opening movement.

Referring to the drawings, l0 designates as an entirety a modern type ofcooking stove or range, in one side of which is a broiler oven,designated as a whole by H. In the upper portion of the oven is a burnerl2 supplied with gas through a manifold l3. l4 designates the top wallof the oven, and IS, the bottom wall. Slidable inwardly and outwardly ofthe oven is a broiler drawer IS, the side walls of which are equipped,as usual, with spaced ledges ll that support the longitudinal edges of abroiler pan l8, in which latter is seated the removable broiler grid l9.The drawer I6 is slidably supported on the oven bottom l5 through theagency of a pair of rollers 20 and 2| on each side. The foremost rollers2| are journaled on the inner sides of a pair of inwardly facing channelbars 22 that are spot-welded or otherwise secured on the side portionsof the oven bottom l5, and the rear rollers 20 are similarly journaledon the lower depending flanges of a pair of Z-bars 23 that are rivetedat 24 to the lower corner portions of the drawer IS; the arrangementbeing such that the rollers 20 and 2| on each side are in the samevertical plane.

25 designates the over door which is hanged at 26 to the bottom memberof the usual frame 21 of the front opening of the oven. A spring 28anchored at its lower end to a fixed member of the stove frame and atits upper end to a curved arm 29, rigid with the door 25, cushions thedownward movement of the door and assists its up movement; such a springin various forms being a common equipment of oven doors.

Describing now those features wherein the present invention mainly lies,on the inner face of the oven door 25 is a short lug 30 which carries afixed pivot pin 3|, on which pin is mounted the outer end of a straightbar link designated as a whole by 32, and shown in isolated perspectivedetail in Fig. 6. In its preferred form this bar is of channel shape incross-section, consisting of a web 33 and rectangular flanges 34 on thelongitudinal edges of the web. 0n the inner end of the link the web hasan up-turned rectangular extension 33'. In the extension 33' is a slot35 that extends transversely of the main body of the link, and in theweb 33 is a somewhat longer longitudinal slot 36 that at its inner endis continuous with the lower end of slot 35.

Attached to the rear end of one side wall of the broiler drawer I6 is aplate 31, and a short bolt 24' is passed through the upper limb of theZ-bar 23, the plate 31, the side wall of the broiler drawer l6 and thelining carrying the ledges I'I, securely looking all of said partstogether. on the top edge of the plate 31 is an upstanding lug 36located above the top edge of the side wall of the broiler drawer, andin the lug 36 is mounted a shouldered and headed pin 39, as best shownin Fig. 5. The diameter of pin 39 is such that it has an easy slidingfit in the link slots 35 and 36. The link is slightly spaced from theadjacent side of the drawer by a pair of spacing washers 40 and 4|encircling the pin 39 on opposite sides of the web of the linkrespectively.

The slot 35, when engaged with the pin 39, renders the link 32 operativeto actuate the drawer from the opening and closing movements of thedoor; while the longer slot 36, when engaged with the pin 39, permitsthe link to have a limited amount of lost motion. This lost mo-- tion ofthe link is necessary to avoid collision of the forward end of thedrawer with the door when opening the latter. To effect the transfer ofthe pin 39 between the slots 35 and 36 at the proper times, I employ adownwardly and forwardly inclined flat cam plate 42, that lies in thepath of the inner end of the link and is conveniently formed as anextension of a top flange 43 on the upper edge of a plate 44. As shownin Fig. 2, this plate 44 has a rear vertical flange 45 that is attachedto the rear wall of the broiler oven by screws 46. The front edge of theplate 44 is preferably bent outwardly, as shown at 41, to prevent anycollision of the plate 31 therewith during the final part of the inwardmovement of the broiler drawer.

Briefly describing the operation, Fig. 2 shows the position of the partswhen the oven door 25 is fully closed. When the door is opened, as itswings from the full line position to the dot and dash line positionshown in Fig. 2, the link 32 moves idly, the longitudinal slot 36 ridingover the pin 39 until the latter is at the outer end of the slot. Atthis time, the inner end of the link has reached the cam 42, and as itslides down the cam, the slot 35 rides over the pin 39, as shown in Fig.4, and this creates an operative connection of the link with the drawer,so that the latter is drawn out to the position shown in Fig. 3 duringthe remainder of the opening move ment of the door. When the door isclosed, the link positively moves the drawer inwardly until the innerend of the link encounters the cam 42 and rides up the latter. At thispoint, the drawer has been fully returned to normal position in theoven. At this time, the door is invthe dot and dash line position shownin Fig. 2. During the final closing movement of the door, the link movesidly inwardly, the slot 36 riding idly over the pin, restoring the partsto the full line positions shown in Fig. 2.

It will 'be observed that the link 32 is supported wholly at its ends onthe pins 3| and 39, and in its to and fro movements does not contactwith or rub against any other parts. This manner of .supporting the linkavoids both wear and noise.

The channel form of the link 32 possesses the advantage that it may bemade very light, as, for example, by stamping it from sheet metal; andat the same time, it is amply stiff and rigid to avoid bending or bowingwhen under the thrust strain of pushing the broiler drawer back into theoven.

When it may be desired or required to entirely remove the broiler drawerfrom the oven for cleaning the drawer and/or the oven, this can readilybe efiected by merely withdrawing a cotter pin 48 that is passed througha hole in the outer end of pin 3|, and slipping the forward end of thelink ofi said pin.

The mere reversal of these operations reestablishes the operativeconnection of the door to the link.

I claim:
